MIRA v0.301.0 — public beta
Pre-releaseMIRA v0.301.0 — public beta
The current public-beta build of MIRA — a self-hostable, single-binary personal AI agent that runs on hardware you control. A project of Vexillon. Licensed under AGPL-3.0-or-later.
⚠️ Public beta (pre-release). Recommended build for new installs; supersedes v0.300.1.
This release begins a series that grows MIRA-Guardian — MIRA's local, fail-closed watchdog — into a fuller safety net. Guardian is off by default and opt-in.
Guardian gets its own voice and a tiered local model
- Its own charter. The watchdog now speaks in a distinct voice — quiet, precise, and non-alarmist — rather than borrowing MIRA's.
- A tiered local model. Guardian runs a light model for routine, low-severity notes and escalates to a stronger model only for real triage. Both tiers are fail-closed and local-only — a cloud model is refused.
- Configure it under Settings → Guardian.
